The dataset was created by Niu et al. based on the copepod dietary experiments (during 2023) and model simulations (during 2024) at the Flanders Marine Institute (VLIZ), Belgium. more Nitokra spinipes was exposed to Poly(lactic-co-glycolic-acid) microbeads (5µm) at 0, 0.1, and 1% of food content, at 22°C and +3°C (IPCC-SSP5-8.5). The obtained filtration rates, a proxy for energy assimilation (assuming constant assimilation efficiency), were used in an individual-based model implementation of the dynamic energy budget theory (DEB-IBM) to extrapolate population-level effects under a warming scenario. Our results indicate a reduction in filtration rates by PLA microplastics at +3°C, with 96-h EC50=0.029%, and the DEB-IBM model indicated a population-level EC50=0.0098% (95% confidential interval: 0.0095% - 0.0102%). Our results suggest that the combined exposure to elevated water temperatures and microplastics induces a decrease in energy assimilation on benthic copepods, with negative effects at population level.
